Pure dub fire for Record Store Day 2013! Originally released in 1975, King Tubby Meets The Upsetter At The Grass Roots Of Dub brought together two of the most influential mixing engineers at the time and helped establish dub music to an audience beyond sound system followers. Rightfully acknowledged as the dub clash of the century, Lee Scratch Perry and King Tubby went head to head in this classic horn soaked dub conference - bringing their own original flavor to one side of record. For the first time since in over a decade, Greensleeves Records has unleashed this ultimate dub clash on vinyl and allowed fans to rediscover why it was the bestselling reggae album in 1975.
